ROTARY lVl-EAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 246,812, dated September 6, 1881.

' Application filedMay20, 1881. (Nomcdel.)

To alt lwhom t may concern:

Be it known that I, DANIEL PETERs, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Rotary Meat- Cutters, of which the following is a specification.

My invention relates to meat -cutting machines employing rotary cutters, and its obio ject is to improve and render such cutters more To this end my invention consists, first, in combining with a rotating cutting-board having a conical upper surface a shaft in the plane of and at right angles to the vertical axis of the cutting board, provided with circular eccentric cutting-disks arranged obliquely to the shaft and parallel with each other, and graduated in size according to their distance from the axis of the cuttingboard, with their cutting-edges in contact with the face of the cutter; second,in combining with a cutting-board, shaft, and disks, constructed and arranged in the manner described, a second shaft similarly provided in the line of the lfirst, but on the opposite side of the axis of the cutting-board and in a similar relation thereto, and means for driving said shafts simultaneously in op posite directions; third, in the combination and arrangement ofthe supporting-frame and driving mechanism of the cutting board and shafts carrying disks.

My invention is embodied in mechanism illustrated in the accompanying drawings, in whicli- Figure 1 is a side elevation of myimproved meat-cutter with the cutting-board in section 5 and Fig.2 is a side elevation of one of the cutter-shafts enlarged, showing the collars in section.

Similar letters of reference indicate similar parts in both specication and drawings.

Referring to the drawings, A designates the supporting-frame, s' s2 the cutter-shafts, C the cutter board, and s3 the pivotshaft on which the cutter-board is mounted. These parts constitutethe principal features of the cutter, the details of which may be described as follows:

The frame A is approximately rectangular, and is supported by feet B, in the usual manlar `bevelpinions,p p2, gearing with an idler bevelpinion,p3, running loosely upon a vertical shaft, s3, arranged in the plane of and between the shafts s and s2, and having its bearings in the upper and lower sides of the fraineA. rlhe shaft s3 projects below the frame A, and is recessed and borne upon the point of a set-screw, b, passed'upward through a loop, c, formed below and upon the lower side of the frame A,the purpose of which construction, as will more clearly appear hereinafter, is to adjust the cuttingboard to the cutters. An auxiliary nut, d, upon the set-screw serves to secure it in position when adjusted.

The cutting-board O is annular, with a conical upper surface, and is secured upon a suitable supporting-frame, c, which is rigidly centered upon the shaft s3 within the frame A, and held to the shaft by a set-screw permitting its ready disengagement for any purpose. At the inner and outer edges of the cutting-board are walls g, extending upward nearly to the shafts, forming a trough, of which the cutting-board is the bottom.

The cutting apparatus proper consists of a series of eccentric disk-cutters, f, preferably of steel, graduated in size to the angle formed between the shafts and the cross-sectional edgeofthecutting-board. rlhesecuttin,f. ;disks are arranged upon the shafts at an inclination to its axis and parallel to each other, the eccentricity and inclination of the cutters being in such relation to the coning of the cuttingboard as that when the shafts are rotating the edges of the cutting-disks shall be always in contact with the cutting-board while traversing paths alternately receding from and approachin g the true center of the cutting-board.

It is also desirable to have the disks so far inclined as that the extreme limits of their cutting-paths shall coincide, and thus cover IOO every portion of the board, as indicated by the dotted lines in Fig. 2.

The cutters are secured upon the shaft in the following manner: Washers or thimbles h, with ends formed to the proper angle, are interposed between the disks, with suitable end washers, h, one fitting against a fixed collar, i, upon the shaft and the other against a nut, j, adjustable upon threads cut upon the shaft, for the purpose of forcing the disks with their interposed washers against the collar t'. Each washer is provided with a short pin, t, projecting from one end and a corresponding recess in the oppositel end, each pin passing through an aperture in the disk and engaging in the recess of the adjacent washer, and that of the last wasl1er,h, into the collar 'i'. By this construction the disks, when removed for sharpening or for any other purpose, may be readily replaced, the pins and recesses forming a certain means of replacing them always in their proper positions, at the same time securing a rigid attachment to the shaft.

The reason for eoning the surface of the cutter'board and graduating the sizes of the cutting-disks is that the path of each disk upon the cutter-board is a circular line of greater or less length, depending on its distance from the center of the rotating cutter-board. Since the cutters of each set are all mounted on the same shaft, and therefore have a common revolution, the diameter of the cuttingdisks must increase in proportion as th eirpaths are longer, in order that they may not scrape upon and wear out the surface of the cutting-board, as they would necessarily do ifthey were uniform in size and the cutter-board fiat.

Another advantage of this construction is that the cutters, when placed at an angle to the axis ofthe shaft, are round, and are simply placed eccentrically upon the shaft, and are therefore easily made and repaired, whereas with a flat cutter-board the disks would be of a peculiar oval shape, whose curves would be diiiicult to adjust and maintain.

The operation will be readily understood. Motion given to the shaft s is transmitted by the bevel-gearing to the opposite shaft, s2, and the respective series of disks, acting upon the cutting-board C, cause it to revolve, carrying the meat placed thereon under the cutters,

Heretofore a series of circular cutters of the same diameter have been arranged upon a shaft placed radially above a flat circular rotating cutting-board, said cutters being set obliquely upon the shaft; but such construction is obviously inoperative, and such is not my invention.

Having described my invention, I claim and desire to secure by Letters Patent'- 1. In a meat-cutting apparatus, the combination of the cutting-board, provided with a conical upper face, and a series of cuttingdisks arranged upon a rotating shaft at an inclination thereto and graduated in diameter to the angle formed between the said shaft and the cross-sectional edge of the cuttingboard, substantially as described.

2. In a meat-cutting apparatus, the combination of the annular cutting-board, provided witli a conical upper face, with two shafts rotating in unison in a stationary framework, and a series of cutting'disks arranged upon the shafts at an inclination thereto and graduated in diameter to the angles formed between the said shafts and the cross-sectional edge ofthe cutting-board, substantially as described.

3. A meat-cutter combining in its structure a stationary frame-work, A, having depending projections a, the two shafts s sjournaled in stationary bearings in the sides ofthe framework and the depending projections, the inclined cutting-disks j', arranged on the said shafts, the bevel-pinions p p2, arranged on the inner ends of the shafts, and the idler bevelpinion p3, by which the power from the driven shaft is transmitted to the other shaft, all sub stantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

DANIEL PETERS.
